necessary for drawing a tabs in Qt 4.1 or above.</p>
<p>An instance of the QStyleOptionTabV2 class has <a href="qstyleoption.html#type-varx">type</a> <a href="qstyleoption.html#OptionType-enum">SO_Tab</a> and <a href="qstyleoption.html#version-var">version</a> 2. The type is used
internally by <a href="qstyleoption.html">QStyleOption</a>, its
subclasses, and <a href="qstyleoption.html#qstyleoption_cast">qstyleoption_cast</a>() to
determine the type of style option. In general you do not need to
worry about this unless you want to create your own <a href="qstyleoption.html">QStyleOption</a> subclass and your own styles.
The version is used by <a href="qstyleoption.html">QStyleOption</a>
subclasses to implement extensions without breaking compatibility.
If you use <a href="qstyleoption.html#qstyleoption_cast">qstyleoption_cast</a>(), you
normally do not need to check it.</p>
<p>If you create your own <a href="qstyle.html">QStyle</a>
subclass, you should handle both <a href="qstyleoptiontab.html">QStyleOptionTab</a> and QStyleOptionTabV2.
One way to achieve this is to use the QStyleOptionTabV2 copy
constructor. For example:</p>
<pre class="cpp">
     <span class="keyword">if</span> (<span class="keyword">const</span> <span class="type"><a href="qstyleoptiontab.html">QStyleOptionTab</a></span> <span class="operator">*</span>tabOption <span class="operator">=</span>
            qstyleoption_cast<span class="operator">&lt;</span><span class="keyword">const</span> <span class="type"><a href="qstyleoptiontab.html">QStyleOptionTab</a></span> <span class="operator">*</span><span class="operator">&gt;</span>(option)) {
         QStyleOptionTabV2 tabV2(<span class="operator">*</span>tabOption);

         <span class="comment">// draw the tab using tabV2</span>
    }
</pre>
<p>In the example above: If <tt>tabOption</tt>'s version is 1, the
extra member (<a href="qstyleoptiontabv2.html#iconSize-var">iconSize</a>) will be set to
an invalid size for <tt>tabV2</tt>. If <tt>tabOption</tt>'s version
is 2, the constructor will simply copy the <tt>tab</tt>'s <a href="qstyleoptiontabv2.html#iconSize-var">iconSize</a>.</p>
<p>For an example demonstrating how style options can be used, see
the <a href="widgets-styles.html">Styles</a> example.</p>
<hr /><h2>Type Documentation</h2><h3 class="fn"><a name="StyleOptionVersion-enum" />QStyleOptionTabV2.StyleOptionVersion</h3><p>This enum is used to hold information about the version of the
style option, and is defined for each <a href="qstyleoption.html">QStyleOption</a> subclass.</p>
<table class="valuelist">
<tr class="odd" valign="top">
<th class="tblConst">Constant</th>
<th class="tblval">Value</th>
<th class="tbldscr">Description</th>
</tr>
<tr>
<td class="topAlign"><tt>QStyleOptionTabV2.Version</tt></td>
<td class="topAlign"><tt>2</tt></td>
<td class="topAlign">2</td>
</tr>
</table>
<p>The version is used by <a href="qstyleoption.html">QStyleOption</a> subclasses to implement
extensions without breaking compatibility. If you use <a href="qstyleoption.html#qstyleoption_cast">qstyleoption_cast</a>(), you
normally do not need to check it.</p>

<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QStyleOptionTabV2" />QStyleOptionTabV2.__init__ (<i>self</i>)</h3><p>Constructs a <a href="qstyleoptiontabv2.html">QStyleOptionTabV2</a>.</p>


<h3 class="fn"><a name="QStyleOptionTabV2-2" />QStyleOptionTabV2.__init__ (<i>self</i>, <a href="qstyleoptiontabv2.html">QStyleOptionTabV2</a>&#160;<i>other</i>)</h3><p>Constructs a copy of the <i>other</i> style option.</p>


<h3 class="fn"><a name="QStyleOptionTabV2-3" />QStyleOptionTabV2.__init__ (<i>self</i>, <a href="qstyleoptiontab.html">QStyleOptionTab</a>&#160;<i>other</i>)</h3><p>Constructs a <a href="qstyleoptiontabv2.html">QStyleOptionTabV2</a> copy of the
<i>other</i> style option which can be either of the <a href="qstyleoptiontabv2.html">QStyleOptionTabV2</a> or <a href="qstyleoptiontab.html">QStyleOptionTab</a> types.</p>
<p>If the other style option's version is 1, the new style option's
<tt>iconSize</tt> is set to an invalid value. If its version is 2,
its <tt>iconSize</tt> value is simply copied to the new style
option.</p>


<hr /><h2>Member Documentation</h2><h3 class="fn"><a name="iconSize-var" /><a href="qsize.html">QSize</a> iconSize</h3><p>This variable holds the size for the icons.</p>
<p>The default value is <a href="qsize.html">QSize</a>(-1, -1),
i.e. an invalid size; use <a href="qstyle.html#pixelMetric">QStyle.pixelMetric</a>() to find the
default icon size for tab bars.</p>
